8-3 Interfaces Deciding Which Interface to Use On some printers, you can attach multiple interface cables to the printer at the same time. The printer automatically switches to the interface receiving a job. Then it prints the job and begins searching the interfaces for the next job. One or more of the following is built into your printer: a standard parallel connector, a USB connector, or a network connector. To use a port, connect a cable from the printer to the computer, then set the appropriate values from the printer control panel or, for network connected printers only, through MarkVision Professional. See your printer documentation for more information. Use a parallel interface when you: • Attach your printer to a personal computer. • Attach your printer to a host system with a Centronics-compatible parallel port. • Attach your printer to a Lexmark external print server. Use a USB interface when you: • Attach your printer to a personal computer, iMac, Sun Ray, or Sun Blade. • Need to connect the printer to a computer that does not have an available parallel port. • Attach your printer to a Lexmark external print server. Attach network cables to Ethernet print servers installed in your printer. Refer to the MarkNet™ Quick Start book or your user documentation for additional setup information. Parallel Interface Use the Lexmark 3.04 m (10 ft) parallel cable part number 1021231, or a cable that is IEEE 1284 compliant, to connect your printer to a personal computer or to a host system with a Centronics-compatible parallel port. See your printer documentation for the location of the printer parallel connector.

Deciding Which Interface to Use

On some printers, you can attach multiple interface cables to the printer at the same

time. The printer automatically switches to the interface receiving a job. Then it prints

the job and begins searching the interfaces for the next job.

One or more of the following is built into your printer: a standard parallel connector, a

USB connector, or a network connector. To use a port, connect a cable from the printer

to the computer, then set the appropriate values from the printer control panel or, for

network connected printers only, through MarkVision Professional. See your printer

documentation for more information.

Use a parallel interface when you:

•

Attach your printer to a personal computer.

•

Attach your printer to a host system with a Centronics-compatible parallel

port.

•

Attach your printer to a Lexmark external print server.

Use a USB interface when you:

•

Attach your printer to a personal computer, iMac, Sun Ray, or Sun Blade.

•

Need to connect the printer to a computer that does not have an available

parallel port.

•

Attach your printer to a Lexmark external print server.

Attach network cables to Ethernet print servers installed in your printer. Refer to the

MarkNet

™

Quick Start

book or your user documentation for additional setup

information.

Parallel Interface

Use the Lexmark 3.04 m (10 ft) parallel cable part number 1021231, or a cable that is

IEEE 1284 compliant, to connect your printer to a personal computer or to a host

system with a Centronics-compatible parallel port. See your printer documentation for

the location of the printer parallel connector.
